nAIsIN-sEEDER.

Specification of Letters Patent.

Application filed April 26, 1909. Serial No. 492,424.

To all whom it may concern:

Be it known that we, MARTIN ERLENBACH and HEINRICH KOHN, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Raisin-Seeder, of which the follbwing is a specification in such full and clear terms as will enable those skilled in the lart to construct and use the same.

This invention relates to a seeder for raisins, prunes and other fruits and its object is to provide means whereby the pin roll may be easily repaired where hard objects, such as rocks, or nails have been accidentally passed through the rolls.

Another object of the invention is to so shape the rolls as to make possible the proper tightening of the pin holding sections on the roll body.

A further object of the invention is to provide means whereby two sets of rollers may be driven on the same stand, one set being taken out of gear with the drive pulley by the removal of a pin.

Other objects of the invention will appear as the description proceeds.

In the drawings in which the same numeral of reference is applied to the same portion throughout, Figure 1 is a plan view, partly in horizontal section of the complete machine, Fig. 2 is a front elevation of the machine looking toward the pin rollers, Fig. 3 is a sectional vview on the dotted line 3 3 of Fig. 1, Fig. 4 is a view showing the construction of one of the pin holding sections and showing three modified forms of pins used, Fig. 5 is a diagram of a system of placing the pins in the pin plates whereby each of the pins is spaced the proper distance from each other pin.

The numeral 1 is applied to the base of the machine, said base having the upstanding bearings 2, 3, 4 and 5 on which the rollers are journaled, the bearings for both of the pin rolls 6 being in the same line. Each pin roll comprises a frustoconical shell 7, the largest ends of the shell being placed near the center of the machine, and

eing secured on a pin 8 which has a ange 9 thereon, said pin being provided with the portion 10, shown in dotted lines and which projects into the hub of the pulley 11, the object being to support the pulley adjacent the rollers and in the proper position to be connected therewith by means of a set bolt 12 passing through a portion of the hub of the pulley and into the flange 9.

Near the largest end of the pin roller there is a flange 13 which is adapted to hold all the pin sections 14 in their proper places,.said flange being annular and eX- tending around the roll. The pin sections 14 comprise a shell which is concentric with the roll surface, but spaced therefrom such a distance as will allow a shell of Babbitt metal to be inserted between the ro-ll surface and the pin section to secure the pins in said section. There are such a number of the sections as seems desirable, a large number being used in order that as small a number of pins may be rendered unfit for use when a stone passes through the machine as possible, each section being separately renewable. The opposite ends of the pin sections are held in lace by means of a boss 15 which has a ange 16 facing in the opposite direction to the flange on the large end of the pin roll. The pin sections are all placed on the pin roll body, the ends being inserted under the flanges at either end of the roll, the screw 17 is then inserted in the boss 15 and into the small' end of the pin roll, and on being tightened the boss is forced tightly over the pin sections and the same are pressed down into close contact with the outer surface of the pin roller, the boss then becomes the bearing for the small end of the pin roller, 'a pair of nuts on the end of the bolt acting to hold the same in a fixed position without loosening.

' The pins are spaced a given distance apart, this distance being such as has been found to be the proper one for the retention of the seeds at the ends of the pins, and to sna the seeds out of the pins, the bar .18 is use said bar being secured to the upstandinf bearings which carry the roll by means o bolts 19. In order that the -meats of the raisins may be pulled out of the pins and dropped a set of wires 20 is used, said set of wires being passed around the conical toothed roll and secured at their ends on a bar 22, a plate 23 being used to hold the wire ends tightly to the bar 22.

On the rear of the bearings supporting the pin rollers there are bearings 24 or the rubber rollers 25, said bearings being adjustable by means of the set bolts 26, and held Patented July 5, 1910.

in a fixed relation to thesupports rmeans Yof set bolts 27. The rubber rollers are formed witha rustoconical shell`28, at thel ends off which are placed the trunnions 29,

, kIllawirng thus described our invention what we claim as new and desire to secure by'Letters` Batent of the United States is as folseries of wires passing around the' rin roller ybetween the series `oi'jpms, kthe en s of Isaid `wires beingV lixed along anlncline whereby the point of delivery othe seeded raisins is Vfor 'the entire length of the roller.

2. 'lna raisin seeder,a pair of frustoconical.. pin rolls, pin sections carried by said `pin rolls, a bearing boss at the smallend'of the pin roll adapted to act as a bearing and ,tightener for the pin sections, a second pair of similar rolls placed with the large ends adjacent the large ends ofthe first pair of rolls one roll in each set having alincd axes, and means to drive one or both of the sets of rolls from a single pulley.

3.-.In a raisin seeder, afpaii of frustoconlical seeding rollsone of whichis provided with removable vpin holding sections andthe other with la rubber surface lin `contactwith the ends of the pins, said pin holdinP sections being held tightly in con-tact with the roll byy having their large end passed into a y groove at the large end of the roll and into `a groove'in a movable bearing boss 4at the 105 --small end of the roll. smailer arc-the number will decrease to yone 44. -In a nais-in seeding roll, a frame, a frus- VA'c oconical shell having'an-annular groove at its large end-,a movable boss adapted to act as a `jo'urnaliai', the small end andjhaving a 110 groove oppositely' placedto the groove at the largelendofthe roll, a plurality of pin sec- 'tions held in place on'the roll by means of the boss at the small end and the groove at the large end; and'wir-es passing around the 115 pin roll and secured to the frame along an incline whereby the raisins. willgbe dolfed V'from the pin roll alongv a vertical-plane substantially parallel with the Vaxis of said roll.

In testimony whereof we have set our 120 handsfthis 17 day of Aril A. D. 1909, in

z the presence of the 'two su scribed witnesses.
